Using Proxmox Cluster in VRack 1.5

Having spent the last 24 hours trying to get Proxmox to play nice with the new VRack 1.5, it looks like it works perfectly, including online live migration of venet based OpenVZ containers, which didn’t work in VRack 1.0.

The configuration makes eth1 the default card for traffic from vmbr0, however allows eth0 to function alongside it so that you don’t loose out on monitoring features. We also route IPv6 traffic through the VRack on vmbr0 and add additional IP ranges for your VM use to vmbr0.

All the configuration that’s needed is done in: /etc/network/interfaces.
